You have to hear from the pure source, give aural reception, and think of it, meditate upon it. Simply by doing this, you are liberated. These are not bluff. Here is the evidence. Simply receive the message from the right source and contemplate and meditate upon that instruction—you are liberated. Chanting and hearing. Hearing and . . . śravaṇaṁ kīrtanam (SB 7.5.23). First hearing, then chanting. Hear from the right source and discuss amongst yourselves, iṣṭagoṣṭhi. Then the perfection.
So, samādhinā anusmara tad-viceṣṭitam, śuci, śuddhyā, śravā, yaśa, satye rataḥ dhṛtāni ghṛtāni yasya bhavān, evaṁ mahā-guṇas tāvad atha urukramasya vidhitaṁ ceṣṭitaṁ līlā samādhinā citta, cittaika, aikāgrena. This samādhi . . . samādhi does not mean something artificial. Here Śrīdhara Swami says, citta aikāgrena. Citta means your mind, or heart, completely absorbed in Kṛṣṇa thought. That means Kṛṣṇa consciousness. That is samādhi. Citta aikāgrena. Ekāgra, without diverting your heart and mind to any other business, if you simply be engaged twenty-four hours in Kṛṣṇa's activities, that is samādhi. That is samādhi.
